I just recently bought the ZigUltras and all I can say is WOW... I have problems with my feet. I have whats called Plantar Fibroma in both feet. I had surgery on one and still need work on the other. At times finding shoes for me that actually feel good and don't hurt my feet can be really tough as I wear a size 13, which makes it hard to find, compounded with my foot problem its even worse. On top of that I have a fairly wide foot so I cannot wear a lot of shoes that everyone else can. I never thought I could find a pair of shoes to walk around in that are this light and comfortable. At first I thought the Z pattern on the bottom was just another gimmick, but I can say for sure that it definitely works. I feel as though the entire bottom of my foot is being carefully cradled by a pillow.
I just want to say THANK YOU!! for making such a good shoe so that I can actually walk around in without pain again :-)
